Cross over is the first way genes are shuffled to give rise to genetic diversity. Cross over takes place in sexual reproduction. The normal way that cross over occurs is chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other.
If they break the pieces at the same locus in the sequence of base pairs, the result is an exchange of genes called genetic recombination and it ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity occurs.
Answer:
Chloroplasts are what give plants their green color. The second major difference between plant and animal cells is the cell wall. While both plant and animal cells have a cell membrane, on plants have a cell wall.
Acids correspond to volatile molecules that release positive hydrogen ions. These ions have a profound effect on the other molecules in foods. Also, they can affect the cells in your body, fortunately, our taste buds help us regulate the number of free hydrogen ions we eat by making us perceive acids as sour tasting.
